The resurgence of spiritual energy twenty years ago was not a natural evolution. A "thing" that has been sealed for three thousand years is awakening under the earth's veins. The aura is the "breath" that leaks out when it loosens the seal. In the Dharma-Ending Age, someone sacrificed the entire human world to suppress it under the Nine Netherworld. Now that the spiritual energy has returned, it means that the seal will be broken. The spirit-eating body in Chen Jin's body has a deeper connection with this seal - he may be the last lock in the world.
